The first time I ever saw something was when I was living in Baltimore county Maryland. I can't remember my exact age but then again I had things happen to me in the apartments my family lived in up and until we moved when I was at the age of I believe 5 or 6.
It started off small army men flying off the porch, toys being broken, lamps getting knocked off the table. Now I remember being extremely scared one night in my room because the door started to creek closed and then out of the wall came a giant black figure. Its eyes looked to be red but could of been my imagination. I just remember it feeling like straight hatred. I bolted into my parents' room and that's where I stayed for the next week. Now we were already in the process of moving when this happened, so by the time I could of had more experiences with it, we were gone.
Now when we first moved onto the house on Joppa Road and my room was still being set up I was sleeping in between my mom and dad and they had a Bible which had Jesus's bust on it. I was staring at the picture of him because I couldn't fall asleep. All of a sudden a bright white light shines around the picture and Jesus floats over with this just amazingly bright white light and tells me that everything will be alright. Of course I'm a child so I freak out and hide under the covers lol. It's funny how covers become our shields of the night. I could still see the bright white light and just laid there staring at it until morning.
And last but not least. Last week I was home alone where I now live in PA. I live with my uncle in a three-story house and I rent out the top half of the house, me and my girl live here. So I'm at home cause I didn't have to work on a Friday surprisingly and I'm the only one here at home now. I haven't had any more experiences in a long while and all of a sudden I hear what sounds like old time country music, bluegrass really, and nobody in this house listen to that type of music. I recorded it for my girl over a Facebook message. I'll have to see if there's a way I can get it on to this site. It was really faint but played for close to an hour until someone else showed up at home.
So, I don't know, you tell me.
You say that your house use to be a schoolhouse. It use to be that 'the school' was also the social gathering place in many areas. Not just for school functions but anything that was for the community - plays, 'socials', fairs, etc. In some places the school even did double duties as the church for Sunday meetings. Perhaps you heard a residual "sound track" of one of the happier get-togethers.
